*多维数组去重，根据变量值组合商品属性。
*数组字段：dim维度，dimName维度名称，sku（value商品属性，shopid商品id）
*假若，变量$shopid = 101;为当前商品id，则希望组合为
*1、所有的维度去重
*2、保留当前商品的颜色属性，就是说樱语粉的商品id是101，另外几个颜色任意保留其中一个。
* 下面两个维度，保留颜色是樱语粉的属性。

function uni($arr){
$tmp = Array();
foreach(end($arr) as $v){
array_push($tmp,current($v));
continue;
}
return array_unique($a);
}
$narr = array_map('uni',$arr);
print_r($narr);去重，保留属性
